It was found how the self-perception of adolescents changes in the process of media activity, and other effects of the development of adolescents in this process were identified, namely the formation of an adolescent community as an imaginary, and on this basis a real community, organization of teamwork based on self-determination, control over specific functions and tasks of team members to create the final media product. By media activity, we mean a special kind of human activity, characterized by the use of specific media tools and the construction of a special media space, which any sphere of reality can become. Any activity addressed to an imaginary community (according to Anderson) can be considered as a mea-activity. For example, the creation of a literary and any other work of art, shooting a video, etc. The addressee is implicit, he is in the imagination, and the author must look at himself from the position of an imaginary addressee.
